This invention relates to sanitary drink- Such cups are ordinarily arranged in stack formation and placed in a holder in such manner that they may be removed one by oneV from the bottom of the stack.

It is an object of the present invention to provide a one-piece drinking cup of the kind referred to having a tab at the lower` end thereof which may be seized for facilitating withdrawal 'of each cup singly from the bottom of the stack.

lt is a further object of the invention to provide a one-piece drinking cup of the kind referred to having a large volumetric capacity as compared with the surface area of the material required for manufacture of the cup.

It is a further object of the invention'to provide a one-piece cup having a generally conical body but a polygonal base` (preferably square) rlhe body of a cup so shaped will have considerable rigidity and will not, therefore, be likely to collapse in the hand.

Other objectsand advantages will hereinafter appear.

In the drawings fication,

Figure 1 is a view in rear elevation ofa finished cup embodying the present invention;

Figure 2 is a view in front elevation of a stack of-cups like that disclosed in Figure 1;

Figure 3 is a plan view of the cup illustrated in Figure 1.

Figure 4l is a bottom plan view of the sam cup;

Figure 5 is a view in rear elevation partly broken away of a cup similar to that of Figure 1 but having a beaded rim and having the bottom tabs folded in;

Figure 6 is a fragmentary plan view of a paper web killustrating how the cup blanks are cut;

Figure 7 is a view of a completely cut but unfolded blank associated with the former on which it is folded;

Figures 8, 9, 10, 11, and 12 are fragmentary views illustrating the succeeding steps which forming part of this speciresult in the completion of the cupof Figure 1.

Referring first to Fi ures 6 to 12, the blanks 1 are first cut in the orm shown in Figure 6 from a paper web 2. Each blank has an arcuate upper-edge 3' and an arcuate lower edge 4. The lower edge 4 is discontinuous, the

lower margin being indented by notches 5 and 6 to facilitate the subsequent formation of the cup bottom and the folding of tabs. After the blanks have been 'cut :in the form shown in Figure 6, they may be regarded as divided along the line 7 and also along the lines 8, 9, 10 and 11 to dene tab aps 12 and 13 and bottom ap's 14, 15 and 16. This is a purely imaginary subdivision, however, referred to' at this point for facilitating the ensuing description. The tab dan 12'may also he regarded as divided along lines 17 and 18 and the tab flap 13 maybe regarded as divided along lines 19 and 26. Adhesive 21 is applied to the tab flaps and tothe bottom flap 1i as illustrated in Figure 7, and adhesive 22 is applied to a margin of the body and to the bottom flap 16 as i ustrated in this-figure. The upper edges of the aps 12, 15 and 13 are of equal length and would form chords of a Y circle drawn concentric with the upper circular edge 3 of the blank. 'lhe upper boundaries of the bottom `laps le and 16 would also forni chords of this circle but they are not necessarily of the same lengths as the other chords referred to since in the finished cup these flaps overlap one another, the combined eective len h of the upper edges of the two aps being t en equal to the le h of the upper edge of any one of the oter a s.

greparatory to folding, the blank is associated with a former 23 as illustrated in Figure 7. This former may be described roughly as generally frusto-conical in shape but it is not really so because the genera tantially circulary cross and the shape of the former is such that its perimeter at any point is equal to the circumference taken at a corresponding height on the frustrum of a cone having the cir- 5 cumference of the larger base thereof equal to the circumference of the rim of the finished cup illustrated in Figures 1 to 4 and having the circumference of the smaller base thereof equal to the perimeter of the square base of the cup. ln other words, the blank, which is obviously adapted to be wrapped upon the frustum' of such a cone, is also adapted to be wrapped snugly upon the former as illustrated and to lit it at every point. When the blank 1 has been associated with the former 23 in the manner illustrated in Figure 7, the

left hand wing of the blank is folded around the former to the position shown in Figure 8. The right hand wing of the blank is then folded around the former to the position Y shown in Figure 9, thus bringing the adhesive 22 into engagement with the outer face of the body and with the bottom flap 14 of the blank. The flaps 14 and 16 now form jointly a rear bottom ilap which is next folded in against the dat bottom of the former as illustrated in Figure 10. The front bottom :Sap 15 is then folded in against the bottom of the former so that the adhesive 15 lies against the outer face of the rear bottom flap. As an incident of the folding in of the frontY and rear flaps, the lines 8 and 9 are brought into coincidence with the left lower edge of the former and the lines 10 and 11 are brought into coincidence with the right lower edge of the former. At the same time, the tab flaps are folded along the lines 17, 18, 19 and 20, these lines dening the lower boundaries of the side tabs. The

notches 5 and 6 facilitate the folding and correct forming of the tabs and obviate the overlapping of an objectionable number of thicknesses of paper on the tabs'. The side tabs are illustrated in .Figure 11 as extending outward horizontally, and in Figure 12'as folded up against the sides of the cup. They may, if desired, be pasted against the sides of the cup and be utilized as abutments or thrust members to be engaged by mechanical Separating means for withdrawing the cups singly from the stack. This completes the manufacture of the cup so that it may now be removed from the former and placed in a stack as illustrated inFigure 2. The cup manufactured as described has a large volumetric capacity for the amount of paper used, because the base as well as the top of the cup is of substantial cross sectional area. The blanks, moreover, are of regular shape so that little waste of material is involved in cuttingthem from a web.

The tabs 12` and 13 when folded u as illus'- tratedl in Fi re 12 serve two ctions: They space t e body portion of each cup from the body portion of the next one above it in the stack, sufficiently to prevent the lowermost cup from frictionally dragging the next cup down with it; and they also provide means whereby the cup may be moved outward without the necessity for squeezing the body portion of it.' The tab is located at the very bottom of the cup and is, therefore, ideally situated for applying tractive force to the cup without likelihood of binding the cup against the cup next above it in the stack and without liability of disarranging the stack.

ln- Figure 5 disclosure is made of a cup similar in all respects to the cup already described with the exception that the tabs 12 and 13 are folded inward against the bottom of the cup instead of outward and upward against the sides as in Figure 1, and with the further exception that the upper margin of the cup is rolled to form a beaded rim 24.

I desire it to be understood that various departures from the specilic embodiment described in detail will occur to those skilled in the art without, however, violating the spirit of my invention nor departing from the scope of the appended claims.

. claim:

1. A non-collapsible sanitary drinking cup, adapted to form one of a nested stack of cups, comprising a body portion of tapering cross section, bottom iiaps folded inward and adhesively connected to form a flat base, and means forming an integral pull flap at the lower extremit of the cup, which serves r to space the cup the stack.

2. A non-collapsible sanitary drinking cup comprising a bodyportion of tapering cross rom an adjoining cup of section, bottom flaps folded inward and adhesively connected to forma fiat base, and means'forming a pair of integral pull flaps at opposite sides of the lower end of the cup, said pull ilaps overlying the lower margins of the sides of the cup and servin to space the body portion thereof from the ody p0rtion of a similar cup in which it is inserted.

3. A non-collapsible sanitary drink cup comprising a body portion of tapering cross section, bottom flaps integral therewith,

folded inward and adhesively secured together to form a at base, and plural ply pull tabs also integral with the body portion and directly connected with the bottom flaps toassist in sealing the bottom of the cup, and to space the cup from an adjoining cup of the stack.

In testimony whereof I have aixed my signature to this specification.
